METHOD OF SEISMIC-ACOUSTIC QUALITY MONITORING OF EMBEDDED BUILDING STRUCTURES CONCRETING Russian patent published in 2020 - IPC E02D7/04 G01V1/00 G01V1/28 G01N3/32 G01N33/38 

FIELD: construction.

SUBSTANCE: invention relates to construction of buried reinforced concrete or concrete structures erected by means of "wall in ground" method in soil, as well as control of quality of concreting of said structures. Seismoacoustic source 5 generates seismoacoustic waves at different points of first hollow tube 1 due to its movement at intervals of 0.5 to 4 meters over the length of pipe 1, wherein seismoacoustic source 5 is connected and synchronized with seismoacoustic receivers 7 by digital seismoacoustic station 8, signals produced by seismoacoustic receivers 7 are recorded when seismoacoustic waves pass through the hardened concrete medium of the "wall in ground" structure 4. After tomographic processing of information in the form of a kinematic cut in the vertical plane and a design section on the strength parameter of the hardened concrete medium of structure 4, decisions are made on options of elimination of detected defects of concreting 9 of structure "wall in ground" 4, then hollow pipes 1 and 2 are removed from structure "wall in ground" 4 and concreting of formed wells is performed.

EFFECT: possibility of detecting defects of concreting of buried reinforced concrete and concrete structures erected by the "wall in ground" method, as well as high reliability of determining presence of defects of concreting of buried building structures "wall in ground" due to cross scanning of defects from different points along height of structure.
